[Old Fr.] A shell-fish radially ribbed, and having the edges of its two-valved shell formed into a series of small curves. The shell is light, and the fish has a little air-bag which enables it to float. It abounds on the English and American coasts, and on the shores of Palestine. Formerly the shell was used to cook Oysters in. An edible scallop is found on the Atlantic coast of the United States. The shell of the Palestine species was formerly worn by pilgrims to show that they had visited the Holy Land.
